Hello,I am using an STM32U585CIU6 with LSM6DSOX to sample acceleration values, in order to use it in a project on NanoEdge. I am facing an issue while trying to sample higher frequencies. My accelerometer is set to operate at 833Hz. By printing the n...

Hello,I want to use a OV7670 camera module with my STM32U585CIU6, which has no support for DCMI. I've been trying to do an I2C address scan but I can't get the camera address. I'm using a custom board with 3 other modules that are properly identified...

Hello,I want to use an OV7670 camera with my STM32U585CIU6 MCU. I've done all connections but failed to identify the camera module with I2C. I have then removed the wiring and just kept the following connections: 3.3V supply, GND, SCL and SDA (pull-u...

HelloI am starting a project with a STM32U585CIU6 and an OV7670 camera module. I want to use the DCMI interface to get the data, and I'm using the Introduction to DCMI to STM32 MCUs document as a reference.STM32U585 datasheet mentions the support to ...

Hello,I am working on a Human Activity Recognition model with a STMU585CIU6 using Cube AI. In summary, my model takes accelerometer data from my lsm6dsox sensor, and use a frame of 2s of sampling (for ODR 104Hz, it takes 208 samples) as input for the...

Hello,Thanks for your reply. I managed to get a 833Hz sampling rate by adjusting the Cortex System timer to 8MHz. Furthermore, I started switching my I2C, UART and System Clock to find out which setup is enough to sample data at 6667Hz, the maximum v...

Update:I have tested a LCD screen module with my board, and I obtained the expected i2c addresses. I've also tested the OV7670 with the PWDN/RESET connections to GND and 3.3V, respectively, but couldn't solve the issue. The problem seems to be somewh...

Hi Daniel, thanks for your reply. I had the third parameter set as NULL before, but my problem still persisted. Instead of getting the predicted outputs equal for all classes, using "ai_network_create_and_init(&network, acts, NULL);" gives me an infe...

Hello Andrew,I'm sorry, I actually didn't expressed myself correctly. My point of choosing Arduino instead of STM Cube IDE is just for a matter of convenience: I have some libraries included in Arduino that would require some work for me to actually ...

Hello Julian,I managed to solve the problem. My project settings was set to Multiple instead of Generic. I read that when recording data for "Multiple Sensors" option, I can't use this same approach of using a buffer to store the data, that's why I w...
